Abstract
An improved filter bucket for a flight conveyor having two sides and a bottom with an integral rake edge. Numerous equally spaced apart arcuately curved wires are fixed to and supported by longitudinally extended cross bars in a grid fashion to form the generally concave bucket bottom interior surface. The wires extend beyond the cross bar at the leading edge of the bucket to form a rake edge for engaging and retaining material conveyed. Perforated sides with numerous holes formed therethrough of diameter equal to the bottom grid spacing wires provide for a uniform filtering action filtering action through the bottom and sides of the bucket.
Claims4
An elongate bucket means for use as a flight step on a moving conveyor for filtering refuse from a liquid medium after moving into and out thereof so as to allow the liquid medium to pass through the bucket while retaining the refuse therein comprising:
- a plurality of spaced apart elongate wires extending in substantially parallel manner longitudinally of the bucket means, one of said wires defining a lip on said bucket;
- a plurality of elongate wires extending laterally of the longitudinally oriented elongate wires and in fixed contacting relation therewith, said longitudinal and lateral elongate wires disposed in laterally concave configuration;
- side means for closing the ends of the bucket means and structurally affixing the longitudinal elongate wires into an integral unitary body;
- and
- a plurality of said laterally oriented elongate wires extending beyond the lip of the bucket to define a rake edge on the bucket for engaging and retaining debris contacted by the rake edge.
